To all 'whom it may concern.

Be it known that I, ALFRED E. RICnARus, a subject of the King of Great Britain`2 residing at Leicester', in the county of- Leicester, England, have invented certain new and useful Improvements in Shoe-Sewing machines such as are used in the manufacture of boots and shoes for sewing together the upper and sole of a turn shoe, or the welt, upper and insole -of a'welt shoe.

The object of the-invention is to providey a novel and improved machine which is adapted to operate upon an unlasted shoe, the sole or insole of which is provided lwith a channel, or channel lip by which the upper is secured to the sole.

The invention accordingly contemplates the provision, in a machine provided with a curved hook needle and coperatingstitch forming devices, of a work support adapted to ente-r an unlasted shoeand support successive parts of the sole margin as they come to the sewing point and opposed devices,-

adapted to engage respectively/'the unlasted upper and the inside of the channel lip to hold them in 'correct position with relation to the stitch forming devices.

Since it is desirable that the upper, before being stitched to the channel lip, should be pressed down into the anglebetween the feather of the soleand tlechannel lip, itis`r preferred to arrange the upperengaging'/ device so that it shall have a wiping movel ment inward over the upper toward 'the' channel lip to lay thc upper into the angle.I

between the feather and thelip, and finally` hold it against thelip, thus permitting thev needle to sew the two closely together at the base of the lip. It is also preferred to move the upper-engaging device in the direction of feed so that it may assist the needle, or

other feeding devices in feeding the Work.

The various features of the invention will be readily understood from an inspection of the accompanying drawings and the following detailed description of the mechanism illustrated therein.

In the drawings, Figure 1 is a side view of a machine embodying thev features of the :of the head 2 and surrounds spindle 8 upon which it is capable of being invention in their preferred form; Fig.- 2 1s an enlargedside elevation showing the parts operating immediately upon the work;

` Fia. 3 is a horizontal section view on line 3-3 of Fig. 2 with certain parts broken away: Fig. 4 is a front elevation of thesame, omitting the work supporting horn; Fig. 5 is a vertical section on line 5-5 of Fig. 3;

`and Fig. 6 is a vertical section showing a chine. `The stitch formingdevices are mounted on a head 2 and include the usual hook needle 3 and looper 4. The machine is provided with a work support adapted to enter an unlastcd shoe and progressively engage that part of the inner face of the sole which is adjacent to the sewing point. As shown, the support is in the form of a horn 5 shaped to enter a shoe, and preferably so mounted that it may be rotated to bring different parts of the shoe into operative relationship with the sewing devices. The 'horn is also connected with a treadle by which it may be depressed for the reception and removalvof the Work, and is also automatically depressed by mechanism to be hereinafter described to enable the work to' be fed. As shown, the horn' is rovided with a sleeve 6 that is 'received ithin a bore in a bracket 7 projecting from the base a supporting rotated, for which purpose a ball bearing 9 A'is provided between the lower end of the sleeve 6 and an enlargement l0 of the spindle 8. Relative vertical movement between the spindle and the sleeve is prevented by the boss 1l fixed to the spindle 8 by a bolt 13, this boss engaging in a recess in the upper' end of the sleeve. cient lengthto permit of an up and down motion inthe bracket 7 and is raised and lowered by a toggle 14, 15 the upper end of the link 14 being connected with the spindle 8 at 16 While the lower link 15 is pivoted at 17 in the bracket 7 and is in the form of a bell-crank: lever the outwardly extending arm 18 of which is connected with a treadle The sleeve 6 is of Sullithat the curvedhorn is normally held in raised position by the spring 153 but that 1t can be lowered for the removal, insertion or manipulation of the work bythe t breaking of the toggle by lowering lthe rod through the operation of a treadle to which the rod is connected. The. horn is curved as aforesaid so as to extend within the shoe.

and is provided at its upper end with a button Q5 that forms a. support for the shoe sole.' lln 'the present construction the button is circular in plan and its upper surface is plane.

lt is to be understood that in the use of the machine constructed according to this invention forthe manufacture of'soled turn shoes the edge of the upper overlaps the edge of the sole and in this position theyar'e presented to the machine to be sewn and are afterward turned inside out.

ln the illustrated embodiment oi' the invention the work is fed by the needle 3 which is of the curved type that in penetratingmoves in the arc of a circle. For thus'i'eeding the work the needle carrying lever is mounted on a bracket 43 depending from a slider il that is adapted tobe moved horizontally toward the left hand side of the. machine after the needle has.

pene rated the work to feed the Work,'suit 'able mechanism being provided to' accomplish this movement. To allow the feeding movement 'of the work b y the needle the horn is lowered and this is cii'ected by connections between the needle-actuating; mechanism. and the horn-lowering device. These h connections may comprise a link connectcd at one end fto the lever -iG by which the needle is'oscillatedthrough its arc and at the other end to an arm el? loosely mounted at l7 ,on the stud or spindle on which is mounted the bell-crank lever forming the lower oler-nent l5 of the toggle. 'The lever 4:6 is pivoted at .8 to the machine frame and carries a cam roll lll) that stands in a groove cut in the side of a cam disk mounted on the main shaft. The movements thus imparted to the lever Il() are communicated to the needle by a link universally jointed at on'e end to the ncedlecarrying lever 42 and at the other end to the lever 46. The universal .joints permit the lateral movement of -the needle to feed the work.. The arm 4:7 has ln order thatv the upper messes .adjustably secured to itE by a screw and slot connection, a plateal having a laterally projecting tappet 52 which operates on an extension 58 of the arm "i8 ci theibell-cranh lever 15. 18 and sufficient 4 lost motion. is provided between the contacting surfaces te provide a lowering of the horn merely sutil cient to enable the work to be fed `freely.

The adjustment of the plate 5l on the arm 4T 'enables the opepator to. vary at will the extent to which the horn is lowered during the feeding movement. To prevent the treadle rod vfrom being moved While the horn is automatically lowered for the feedingof the 'work the connection between the tra treadle rod 20 and the arm 18 of the belij crank lever is constituted by a. pint-l projecting from the latter that entersaslot 55 in the tredle rod which is normally main# tained raised by a spring 56 that connectsv it with a projection uponthe frame. A stud 57 carried by the ltreadle rod Q0 limits its upward movement by contacting with the said projection.

A channel lip support is formed by a bracket 72 that is iXed to the machine frame just behind the horn 'top`and has an extension projecting forwardly from itsupper end suiliciently to overlie the top of the horn.A This extension is provided with a' downwardly projecting lug;- il that is shaped to 'support the linner'side of the channel lip against the action of the needle' 3 and of a clamping, pressing or wiping device 75, The said lugvl is proportioned. so as to project downward to support the whole of that portion of the channel lip upon which it acts but as the needle passes underneath the said 'supporting lug when penetrating the work to form a` stitch and as the needle remains in that position dui-ing lthe feed ing movement, the said lug is cutaway at its center so as teclear the needle and thus at this part projects downward to support only the upper port-ion of the channellip and not the base. Thusthe needle may passi i freely under the lug as it moves to feed the work.

sewed as closely as possible to the hase of the channel hp a special form of presser material may he j foot or clamp 75 is provided to move forward, and to wipe over and clamp the upper material tightlysgainst the base of the lip of the channelpiind preferably clamp 75. is

the lip on both sides of the place atwhich the. needle Will operate. This clamp is cut away at 7th so that it does not cla-mpin front of the needle and its yacting front edges are serrated as shown in Fig. 3 in order that it ntiay obtain a better grip of the material at those places where it acts to clamp the upper laterally against the chain nellip that is sustained by the support 70.

'i2-c of suiiicient breadth to clamp the upper to' masses @hviciisly during the feeding'of theworl this clamp will either have to be retracted torelease fthe 'work for feeding orl will'have to move with' 'tlie'work during the feeding operation.r lin thefpresent instance it is pre- Ligerred that it should operate in the latter manner and so assist .in feeding the work and accordingly means are provided to cor .relate its movements with those of the needle. i

lhefclampis.formed upon the end of a slide har 78 whichis carried in guideways i in acarrier 79 '(lTig-, 2) and this slide bar isfad'apted to ,contact with the upper end of a lever 82 pivoted to a bar 83 adjustahly mounted lupon the frame of the machine, the end of the, lever belowits pivot being attached to a spring- 85 which at its other end is .attached to the frame'o the machine. This spring is strong enough to overcome 'th-e action of the spring 8O acting between 'tire .slide barr78 and its carrier 79 so that were it not |for other means acting upon the slide har the latter would normally be held forward in clamping position. |This, however, is not desired and accordingly there is fixed-upon the lever pivot a curved arm v86 lia-ving at its upper end a roll 88 adapted to contact with an edge cam .90 carried by the spindle of the needle segment 4t2, thecam being so located upon the lsegment and so shaped that when the needle 3 is out of the worlr the cam will act to throw the upper end of the lever 8:2 rearwardly against the action of its spring S5 and so will permit the slide bar spring 80 to act to retract the slide har,y and consequent-ly the clamp, from clamping position. lt will be noticed that the clamp is moved vieldingly both toward the work and away from it.A f

En order that the clamp may be' given lateral movement to accompany the needle;i.n its feeding ction the carrier 79 uponvwhich the slide bar 78 is mounted is itself mounted in grooves Fig. 5 at right angles to the guideways hy which it carries the slide bar. these grooves being formed upon a vframe 92 bwhich is carried by, and isfcapable (by means or' a slot and a` screw provided with a handled nut 93) of vertical adjustmentwith relation to the, head 2 .of the machine.

The carrier that controls the lateral position of"the clamp isnornial'ly held in one I direction by means of a spring 9% attached at one end to a pin fixed to the carrier and at the'l other end to a pin fixed to theverti-y cally adjustable frame 92. Mounted upon bracket i3 is a. bent arm whose free end projects .backwardly and downwardly to one side of the slide bar. carrying guideways in the carrier', the arrangement being l'such that the carrier 79 is moved positively by thehent arm 95 in the direction to 'feed the' work and is yieldingly returned by its spring 9i to initial position.

Theoperation ot1 the machine is as follows: The work is placed in the machineI with the channel lip of the sole and the margin or' the upper located between thev projecting lug 74 of the channel lip support 7 0 and the feeding clamp 75, the extremities of the channel lip support being permitted rto rest upon the sole. The upper is manipulated by the fingers-into the correct position, gaged vertically, it may be by the neck Vof support 70, and then the clamp advances and wipes the upper over the feather and clamps it againstithe channel lip which is supported by the lug 7l; the needle at the y'saine time advancing and finally penetrating the work. After this the horn drops to release the work. The needle then moves laterally to feed the Work and the clamp cooperates with it, maintaining a yielding pressure on the margin or the upper that permits the Work to .slide over the surface of the channel lip support which is inadesufficiently wide to support the lip adequately during the whole .of the feeding stroke At the finish of the feeding stroke the horn rises to support the work; while the looper operates, the clamp, then moves backward to release its grip, and finally both needle and clamp are returned laterally of the machine to their starting position.
